Beschreibung
Zusammenfassung:	A non-stoichiometric glass composition having greater than or equal to about 50 mol. % to less than or equal to about 95 mol. % GeX2; greater than or equal to about 0.5 mol. % to less than or equal to about 35 mol. % Ga2X3, In2X3, or a combination thereof; and greater than or equal to about 0.5 mol. % to less than or equal to about 40 mol. % RX. R can be an alkaline earth metal. X can be present in a non-stoichiometric amount and can be selected from Se, Te, S, and combinations thereof. A method for making a non-stoichiometric glass including forming a GaGeX precursor material, grinding the precursor material, loading the ground precursor material with an alkaline earth metal component, and forming an alkaline earth metal GaGeX glass.
